The square panel mount design provides a flush, professional finish on equipment panels. The twist-lock mechanism accepts NL4FC cable connectors — a quarter-turn locks the cable connector to the panel socket, preventing accidental disconnection during live performance.

Cut with a router, oscillating tool, or drill press with a square punch. The mounting flange overlaps the cutout and is secured with two M3 screws through the flange holes. Verify the cutout dimensions against the specific socket datasheet before cutting — dimensions may vary slightly between manufacturers.\u003c\/p\u003e\n\n\u003ch4\u003eCan I use this socket with 2-pin Speakon cable connectors?\u003c\/h4\u003e\n\u003cp\u003eYes. 2-pin Speakon cable connectors (NL2FC) mate with 4-pin panel sockets using the 1+ and 1- contacts. The 2-pin connector physically fits into the 4-pin socket and locks correctly. The 2+ and 2- contacts in the socket remain unconnected.\u003c\/p\u003e\n\n\u003ch4\u003eHow do I wire the panel socket?\u003c\/h4\u003e\n\u003cp\u003eThe panel socket has solder terminals on the rear labeled 1+, 1-, 2+, 2-. For standard mono amplifier output: solder the positive amplifier output wire to 1+, and the negative (return) wire to 1-. Leave 2+ and 2- unconnected for mono applications. For bi-amp: connect LF amplifier output to 1+\/1-, HF amplifier output to 2+\/2-. Verify the speaker cabinet’s internal wiring matches the bi-amp pin assignment before connecting.\u003c\/p\u003e\n\n\u003ch4\u003eAre these compatible with genuine Neutrik NL4FC cable connectors?\u003c\/h4\u003e\n\u003cp\u003eYes. These sockets follow the Speakon standard and are mechanically compatible with genuine Neutrik NL4FC cable connectors. For touring and rental applications requiring guaranteed compatibility and maximum reliability, specify genuine Neutrik NL4MP panel sockets.\u003c\/p\u003e\n\n\u003ch3\u003eTypical Applications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePower amplifiers:\u003c\/strong\u003e Rear panel speaker output connections\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpeaker cabinets:\u003c\/strong\u003e Input socket for passive speaker cabinets\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStage rack equipment:\u003c\/strong\u003e Speaker distribution panels, patch bays\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCustom audio enclosures:\u003c\/strong\u003e DIY amplifier and speaker cabinet builds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInstallation audio:\u003c\/strong\u003e Fixed speaker system connection points in venues\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003ePackage Contents\u003c\/h3\u003e\n\u003cp\u003e4, 10, or 20 pieces (select above) — 4-pin Speakon square panel mount sockets (NL4MP compatible).
